Schneider Electric 8501xte Time Delay Relay 120V AC

Schneider Electric's Square D 8501XTE time-delay timer attachment adds an adjustable on-delay timing function to Type X NEMA control relays, using a 120V AC coil for standard control circuits. This timer attaches to compatible 8501X relays and provides timing control via the XTE timer, with model variations offering different contact configurations (examples include 1NO/1NC in some versions and multiple NO contacts in others). The unit is rated for up to 10 A resistive at 600 VAC, enabling it to drive relays, solenoids, or small motors within industrial panels. Timings are set through the timer attachment, with catalog entries documenting one-minute on-delay variants for the 8501XTE family and a range of settings across other configurations; coil voltage for 120V AC 60 Hz versions is standard in these models. The 8501XTE timer attachment mounts on 0–4 pole AC or DC relays (except XMO master), making it suitable for sequencing in machine tools, conveyors, and automation panels where a controlled startup or interlock delay is required.
